1. An isolated adherent placental stem cell that is:
- CD200+ and HLA-G+;
CD73+, CD105+, and CD200+;
CD200+ and OCT-4+;
CD73+, CD105+ and HLA-G+;
CD73+ and CD105+ and facilitates the formation of one or more embryoid-like bodies in a population of placental cells comprising said stem cell when said population is cultured under conditions that allow the formation of an embryoid-like body;
or OCT-4+ and facilitates the formation of one or more embryoid-like bodies in a population of placental cells comprising the stem cell when said population is cultured under conditions that allow formation of embryoid-like bodies;
or any combination thereof.
